, This invention relates to concealed hinges; and the object of theinvention is to provide a hinge of the class described consisting of twobutt parts, with links 'for movably coupling said butt parts and whereinone butt part is in the -form of a hook-shaped arm' having a housingportion concealing the links of the hinge; a fur-v ther object being toprovide a hinge of the class described, the hook-shaped butt part ofwhich is provided with an attaching plate portion so constructed as tofacilitate quick attachment and detachment thereof with respect to a'supprt` or a supplemental butt part secured toror forming part of saidsupport; a further object/.being to provide a hinge of the. classdescribed which, in

In the accompanying drawing, haveindicated at --IU a'l part of thebodyoi.' a motorkvehicle; 5o and at'I'I, a door mounted in connection withthe body I0 by. 'lone'pofmy improved hingesI I2 shown in Figs. 1`, 2andV` 3 of vthe drawing and wth'a modified form or hinge I2a shown inFigs. 4, .5 and (i.A The door II is provided with a projecting 55ilange- I3 at the hinged side thereof to close the space formedbetweenadjacent walls I4 and I5 of the door and body of the vehiclerespectively. Tir'ehinge' shown -in Figs. 1 to 3 inclusive consists of ahousing butt part I6 anda hook-shaped arm I1 which is movably coupledwith the hous- 5 ing I6 by links I8 and I9 arranged on fixed pivot pins20 and 2I respectively in the housing I6 or the top and bottom'walls 22and 23 thereof,

'whereas the free ends of said links are pivotally supported inconnection with pins 24 and 25 10 mounted' in connection with thehook-shaped butt part II, thepin projecting beyond the upper and lowersurfaces of the link I8 and butt part I1 and adapted to be slidablymounted in arcshaped or semi-circular channels 26 formed on 15 the innervadjacent surfaces of the top and vbottom walls 22 and 23 of the butthousing I6.

' The top and 'bottom walls of the butt housing I6 are joined at onelside by a vertical wall 21 which forms a substantially U-shaped body ofsaid housing. The forward .edges of said top and bottom walls haveiaterallyextending flanges 28 to provide for'the attachment or mountingof said buttv I6 in connectionwwith thefbody I0 of the vehicle bywelding,.riveting or by screws or bolts in customary ways. The grooves26 open v outwardly through one side oi' the top and bottom walls 22andf'23 asindicated at 29,-Fig. 2 `of .the drawing, to lfacilitate themounting of the pin 24j thelEll. l f 30 In` Fig. 3 of the drawing, 'thetop and vbottom walls 22 and 23 are drawn inwardly to form bushings 30around the pins 20, 2| so as to provide.

longer bearings for the pins in said plates, and

at the same time, to provide additional ybearings l 1 sheetmetal partswhichmay be welded or other- `wise secured together, namely, an fouterrelaf tively thin hood part 3| and an inner heaviery elongated strip'orsheet 32 fashioned toform the desiredcurvature of. the hook-shaped partI1.

The-outer side wan sa ofthe part al is of a simil bearing 34 which iitswithin arecess 35 formed 50 rat the corresponding end portion of thelink I8 in the manner clearly illustrated rin Fig'. 3 of the drawing.The central portion of the part 32 is cut. and curled to formanothercylindrical pintlel bearing 36 arrangedin the same 55 6.0.18 and I9.

butt member or'housing Ila substantially simi- 31 formed in the link. I9as indicated in Fig. 2. 'Ihe upper and lower edges of the part 32 and 5upper and lower surfaces of the links I8 and I9 iit snugly within theupper and lower walls 38 and 39 of the' hood part 3I of the butt I1.

These walls are of the contour clearlyindhated in Fig.,1 of the drawingand form a chamber or recess inwardly of the part 32 and between thewalls 38 and 39 in which the links I8 and I9 are concealed. From thepoint 4|! at the free end of the butt part` I1 to the point 4I, the vouter wall 33 of the part'3I covers and conceals the hinge parts'attheouter exposed sur.- *facethereot so as to render the links I8 Vand I9substantially invisible from the door` opening when the door` is in openposition.

'I'he other end of the part 32 is provided with an angularly arrangedattaching: plate portion. 425having upper and lower projecting anges 43'over which the topandbottom plates 38 and 38 are adapted to pass, andpins 44 are adapted to be passed through the plates 38, 39, ilanges 43,and through amounting plate 45 for detachably coupling the butt I1 withthe door II.

The plate 45 is welded, rivets or otherwise secured-to the wall I4 ofthe door to constitute a lmore or less permanent part thereof andprovides means including the pins 44 for detachably mounting the buttI1.

By reason of the construction employed, the;

butt I1 may be produced at a very nominal cost, especially in employingthe thin shell or hood part 3| which may be readily shaped into theU-shaped cross sectional contour employed throughout the length of thehook-shaped arm portion of said butt, whereas the heavier part 32 simplyin the form of a strip which is curled to form the pintle bearings 34and 3 6 and 'fashioned to form the attaching flanges.' Where directconnection of the part I1 with the supportl'is desired, the flanges 43and plate 45 is eliminated. However, in some forms of construction, itmay be desirable to construct the hook-shaped butt partfrom a singlebody. in which event, the same may be formed from a heavy sheet ofmetalby die forming or coining or by a forging operation, o'r in somecases, the same may constitute a cast or molded body.

In Figs. 4, 5 and 6 'of the drawing, I have shown at 48 a buttmember-substantially similar -in general contour to the member I1 shownin Figs. 1l to 3 inclusive, but which consists in a unitary body havinga continuous outer side wall 41 having top and' bottom walls 48 to whichthe links I8a, I9a.are pivoted on pins 24a, 25a. The ends of the links18a, I 9a arranged on said pivot pins. are solid and not cut away aswith the links The pins 24a and 25a are supported )n the top and bottomwalls 48 ofthe butt 46.

'ielbutt 48 is detachably coupled with a coupling or mounting plate 45asubstantially similar tothe plate 45,v by pins 44a which pass downwardlythrough the walls 48 or upper and lower extensions48a thereof which formmount# ing llanges similar to the ilanges 43 of the butt Withthe hingeshown inFlgs. 4, 5 and 6, a

In said sists of an outer hook-shaped shellportion'5lcomposedA of relatively thinmetal and an inner thicker buttpart 52 in the form of a strip of metal curled at one end to form apintle bearing 53 similar to the bearing 34. The other end Vportion ofsaid strip is extended' angularly to form an attaching plate portion 54which may be screwed, bolted or otherwise secured to a suitablesupDOrting frame. l lindrical pintle bearing 36 shown in Figs. 1 to.3

substituted for the cyinclusive, I employ a cylindrical pintle bearing55 formed on a separate st'rip or plate 56 which r is fashioned to twithin the strip 52'including the attaching plate portion 54 thereof andmay be welded or riveted thereto.

Theother cylindrical bearing of the link 51 operates on a pin 60 mounted inthe butt member 49 as indicated in Fig. 7. 'Ihe link 58 is offsetcentrally thereof as indicated at 6I and with the structure shown inFig. '1. I also,

is provided with cylindrical pintle bearings at its ends, one mountedupon a pin 82 which also passes through the bearing 55 in the top andbottom lwalls of the butt part 5I. 'Ihe cylindrical bearing at the otherend of the link 58 is mounted upon a pin 63 supported in the Links ofthe general constructio of the links 51 may be substituted for the linksI construction of a more economi With all forms of hinges shown,lprovi'de hook'- shaped butt parts having hollow or recessed jside Ysurfaces closed by an outer hood/wall and top and bottom walls whichconceal the links of the hinge from view at the door opening whenthedoor is in open position, thus producing a'neat and nished appearanceand maintaining 'the paint, lacquer or other nish coating which may bl?applied to said hookeshaped'arm as well as type of hinge.

all times. A hook-shaped hinge butt ofthe crosssectional contouremployed will be strong and durablein use, and by reason of the mannerof constructing the same, may be sold at a low price, making it possibleto utilize concealed hinges in the mounting of doors or swinging membersin connection with their supports, whichV would otherwise be impossibleby virtue of the cost of production of hinges' of the concealed typeunder the methods heretofore known.

In addition to the strength, economy and .apf

ished appearance at all times. My invention is not limited to theparticular cross sectional contour of the hook-shaped butt member hereindisclosed, nor to the specic form and arrangement of the links and thebutt housing employed, as these parts will -be modified to suit theparticularitype of installation employed and the swing or throw of thehinge desired.
